Really sad to hear that the business is closing. Can fully understand the position and wish you both well.
It is a great pity and are sadly missed as regardless of 30% more 'competition' , there are no others that I can think of that offer the diversity of the products and at competitive prices.
As a predominately 1/43 modeller, there does not appear to be any others in UK offering produces Modelling Tools have stocked for so many years.
All the best best for the future regardless π
